Apple patched vulnerability in Mac’s Zoom Client; plans to address ‘video on by default’

After the recent disclosure of the vulnerability in Mac’s Zoom Client, Apple was quick to patch the vulnerable component. On July 9, the same day when security researcher, Jonathan Leitschuh revealed the vulnerability publicly, Apple released a patch that removes the local web server entirely and also allows users to manually uninstall Zoom.

The Mac Zoom client vulnerability allowed any malicious website to initiate users’ camera and forcibly join a Zoom call without their authority. Apple said the update does not require any user interaction and is deployed automatically.

How can Mac users ensure they get these updates?

As the vulnerability was capable of re-installing the Zoom Client applications, Apple first stopped the use of a local web server on Mac devices. It then removed the local web server entirely, once the Zoom client was updated. Mac users were prompted in the Zoom user interface (UI) to update their client after the patch was deployed. After the complete update, the local web server will be completely removed on that device.

Apple had added a new option to the Zoom menu bar that will allow users to manually and completely uninstall the Zoom client, including the local web server. Once the patch is deployed, a new menu option will appear that says, “Uninstall Zoom.” By clicking that button, Zoom will be completely removed from the user’s device along with the user’s saved settings.

Plans to address ‘video on by default’

Apple has also announced a planned release this weekend (July 12) that will address another security concern, ‘video on by default’.

With this July 12 release:

  • First-time users who select the “Always turn off my video” box will automatically have their video preference saved. The selection will automatically be applied to the user’s Zoom client settings and their video will be OFF by default for all future meetings.
  • Returning users can update their video preferences and make video OFF by default at any time through the Zoom client settings.

Zoom spokesperson Priscilla McCarthy told TechCrunch, “We’re happy to have worked with Apple on testing this update. We expect the web server issue to be resolved today. We appreciate our users’ patience as we continue to work through addressing their concerns.”

Regarding Apple’s quick action to patch the Zoom Client vulnerability, Leitschuh tweeted that their willingness to patch represented an “about face”. “it went from rationalizing its existing strategy to planning a fix in a matter of hours”, Engadget reports.
